This application note describes the quantitative determination of paraffins, naphthenes and aromatics (PNA) in spark ignition fuels by the multi dimensional gas chromatography separation approach utilized in the Varian PIONA+ GC analysis system.

This application note describes the quantitative analysis of n- and iso-saturates, n- and iso-olefins, and aromatics in spark-ignition engine fuels by multi-dimensional gas chromatography using the Varian PIONA+™ Analyzer. The system is capable of analyzing and reporting hydrocarbon types (paraffins, iso-paraffins, olefins, iso-olefins, naphthenes and aromatics) based on carbon number or as a total.

This document describes the method of analyzing the 370-550 °C petroleum fraction using the Agilent J&W FactorFour VF-5ht UltiMetal column. The column has high temperature and corrosion resistance, which can improve the signal-to-noise ratio and detection limits.

This is an application note introducing Varian PIONA+ analyzer

This application note describes the use of the Varian PIONA+™ Analyzer for the fast analysis of paraffins, iso-paraffins, naphthenes and aromatics in hydrocarbon streams.

This document describes a method for using GC/MS to analyze off-flavors in wine

This article describes the method of analyzing volatile amines using the Agilent J&W Select CP-Volamine GC Column. The column is coated with a base deactivated non-polar siloxane type stationary phase, which provides a highly inert coating surface with minimal absorption for difficult basic compounds. The column exhibits good peak shape and excellent stability, making it suitable for the analysis of highly volatile and basic substances.

This application note illustrates the successful use of an Agilent J&W FactorFour VF-17ms column from Agilent Technologies, Inc. for the fast GC/MS analysis of most PAHs listed in the EU and EPA regulations.

This document describes the method of high temperature simulated distillation analysis according to the IP507/07 standard. The method is applicable to petroleum products with a vapor pressure low enough to permit sampling at ambient temperature and a boiling range of at least 100 °C. The document provides detailed information on the instrumentation and software used.

This document describes the analysis of antioxidants and UV absorbers using an Agilent J&W FactorFour VF-5ht UltiMetal column. Engineering plastics and other polymers used for consumer goods and technical applications often contain many additives that significantly influence the final properties of these products. Therefore, the quantitative determination of additives is important to provide a complete compositional analysis.

This article introduces the widespread use of fatty acid monoamides as slip agents (lubricants) in the production of polymeric films and as anti-adhesives in the food industry. The advantage of using fatty acid monoamides is their biodegradability. Unsaturated amides show better performance than saturated analogues. Some of these amides are also endogenous bioactive substances and cause sleepiness. The authors separated saturated and unsaturated fatty acid monoamides using GC-Capillary Wide Bore technique.

A sensitive and reproducible gas chromatographic method for ethanol and other volatile organic compounds in serum or plasma was developed using the polar CP- Wax 52 CB column, creating good peak shapes; this can also be seen for ethylene glycol.

This application note describes a method for authenticating Scotch whisky using GC analysis. The method involves analyzing the alcohol components in the whisky to determine its authenticity.

This document describes the separation of fatty acid methyl esters (FAME) on an Agilent J&W Select CP-Sil 88 column. The column has a high polarity liquid phase, which effectively differentiates between multiple FAME isomers.
